Follow-up from https://github.com/dafny-lang/libraries/pull/7#issuecomment-909412689: we agree that while it is reasonable for a Dafny standard library to make limited use of triggers, we want to ensure that Dafny programmers are strongly encouraged to avoid triggers in their own code.
This is currently waiting on PR #25, which in turn is waiting on review from @RustanLeino. Once that lands, @sydgibs has a follow on set of patches to add triggers to the rest of the library.
